It is comprised so that it may be pushed in when the cap 1 is closed, and it will be set to the position (alpha). Thus, in a state where the cap 1 is open (a state where the fuel filler A is exposed to the outside), the lock claw 9 is at the position γ, and a state where the cap 1 is closed (a state where the fuel filler A is closed). Then, the lock claw 9 moves to the position α against the urging force of the spring 12.

  The detection means 7 is for detecting whether or not the cap 1 is in a state of closing the fuel filler opening (closed state), and can detect the angle of the operating member 11 as shown in FIG. It is configured. For example, the detection means 7 is composed of a Hall IC element that detects a magnet fixed to a part of the actuating member 11, and when the Hall IC element detects the magnet, the lock claw 9 is recognized as being at the position α.

For example, the operating means 8 is provided on a handle switch (not shown) or a meter panel. It consists of separate switches such as operation buttons. Since the operation means 8 is for moving the lock claw 9 to the position β, the cap 1 remains in the state where the oil filler A is closed although the lock is released only by operating the operation means 8. It has become. As will be described later, the operation unit 8 can be unlocked on the condition that the determination unit 5 determines that a regular ID code has been received.

  The transmission means 3 transmits a vehicle-specific ID code by radio waves or the like that can be carried by the driver, and comprises, for example, a card-type electronic key that can be carried by the driver. That is, the transmission means 3 is configured to continuously transmit the ID code by radio waves or the like at predetermined intervals by the power source. When the driver approaches the motorcycle while carrying the transmission means 3, the transmission means 3 is disposed on the vehicle side. The receiving antenna of the receiving means 4 can receive the ID code.

  The determination means 5 determines whether or not the ID code received by the reception means 4 is genuine for the vehicle, and is electrically connected to the ECU 6 provided in the vehicle. Then, on the condition that the determination unit 5 determines that a regular ID code has been received, the engine start of the vehicle is permitted and the lock by the lock unit 2 can be released.

  More specifically, when the determination unit 5 determines that a regular ID code has been received and an operation is performed by the operation unit 8, a drive unit such as a solenoid is driven to rotate the shaft member 10, The lock claw 9 is configured to move from the position α to the position β. Accordingly, since the lock by the lock unit 2 can be released on condition that the determination unit 5 determines that a regular ID code has been received, the unlocking operation of the cap 1 is simple and the crime prevention effect is improved. And operability can be improved.

  Moreover, in this embodiment, when the engine of the vehicle is driving, it is configured to prohibit the unlocking by the locking means 2. That is, even if the determination means 5 determines that a legitimate ID code has been received and the operation by the operation means 8 is performed, unlocking is prohibited when the vehicle engine is driven. . As a result, it is possible to reliably prevent the cap 1 from being inadvertently opened while the vehicle engine is being driven, thereby improving safety.

  Furthermore, in this embodiment, when the detection means 7 detects that the cap 1 is not in a state of closing the fuel filler A, the engine start of the vehicle is not permitted. That is, when the cap 1 is in a closed state (a state in which the fuel filler A is closed), the lock claw 9 is pushed from the position γ and moves to the position α, and this is detected by the detection means 7 (for example, a Hall IC element). Can detect whether or not the cap 1 is in a closed state.

  Thereby, when it is detected that the cap 1 is not in a state of closing the fuel filler opening A, the engine start of the vehicle may not be permitted.
